挪威国家建筑技术和管理办公室于1989年发布了新的烟气管理设计指南。该指南部分基于英国烟羽模型和NFPA数据。本文演示了羽流模型的各个方面，以及如何对其进行修改，以考虑高机架存储。还显示了火灾增长，即火灾区域发展与时间的关系。一个非常有趣的方面是烟层温度如何影响排烟口的大小，它简化了排烟口的设计，因此，它产生了一种新的简化方法，用于评估排烟通风和喷水装置组合的效果。本文论证了在使用机械排烟通风时必须考虑的大量烟气。 还显示了排气温度及其对不同堆积方法引起的烟层温度和体积流量的影响。示例说明了如何使用设计方法。五个表格给出了设计依据。最后，演示了一种仅用于火灾后排烟的排烟系统的新方法。关键词:烟雾通风、洒水器、模型、设计、烟雾、气流、温度、仓库、中庭、通风口、尺寸。引文:研讨会，ASHRAE交易，第96卷，pt。1990年3月2日，圣路易斯

The Norwegian National Office of Building Technology and Administration released new guidelines for smoke management design in 1989. The guidelines are partly based on British smoke plume models and NFPA data. This paper demonstrates aspects of the plume model and how it is modified to take account of high-rack storages. The fire growth, i.e., fire area development, vs. time is also shown. A very interesting aspect is how the smoke layer temperature affects the smoke vent size-it simplifies vent design- and, as a result, it has led to a new and simplified method for assessing the effect of combined smoke ventilation and sprinklers. This paper demonstrates the enormous amount of smoke that must be taken into account when mechanical smoke ventilation is used. Exhaust temperatures and their influence on smoke layer temperature and volumetric flow rate caused by different stacking methods are also shown. Examples illustrate how the design method may be used. Five tables give the design basis. Finally, a new approach utilising a smoke ventilation system solely for post-fire smoke extraction is demonstrated.KEYWORDS: smoke ventilation, sprinklers, models, designing, smoke, air flow, temperature, warehouses, atria, vents, sizing.
